Keith Sonnier was part of a group of artists who challenged preconceived notions of sculpture in the late 1960s by experimenting with industrial and ephemeral materials.. In Sonnier’s case, materials ranged from latex and satin, to found objects, transmitters and video. In 1968, the artist began creating wall sculptures using incandescent light and sheer fabric. Frustrated by the standardized forms of incandescent light, he started experimenting with neon. Using copper tubing as a template, Sonnier began sketching lines, arches and curves ultimately realized in glass tubing enclosed neon. The linear quality of neon allowed Sonnier to draw in space with light and color while colored light interacted with the surrounding architecture.
